In the Payload Type field, if the payload type for the coder you selected is dynamic, enter 
a value from 0 to 120 (payload types of ‘well-known’ coders cannot be modified). 
The payload type identifies the format of the RTP payload. 

 

If not specified, a default is used. 

7

 

From the Silence Suppression drop-down list, enable or disable the silence suppression 
option for the coder you selected. 

 

For G.729 it is also possible to select silence suppression without adaptations. 

8

 

Repeat Steps 3 to 7 for the second to fifth coders (optional). 

9

 

Repeat Steps 2 to 8 for the second to fourth coder groups (optional).

Only the ptime of the first coder in the defined coder list is declared in INVITE / 200 
OK SDP, even if multiple coders are defined. 

If the coder G.729 is selected and silence suppression is enabled (for this coder), 
the gateway includes the string ‘annexb=no’ in the SDP of the relevant SIP 
messages. If silence suppression is set to ‘Enable w/o Adaptations’, ‘annexb=yes’ 
is included.   

Tel Profile Settings 

Use the Tel Profile Settings screen to define up to four different Tel Profiles. These Profiles 
are used in the ‘Trunk Group’ table to associate different Profiles to gateway’s B-channels, 
thereby applying different behavior to different gateway’s B-channels. 

To configure the Tel Profile settings: 

1

 

Open the ‘Tel Profile Settings’ screen (

Protocol Management

 menu > 

Profile 

Definitions

 submenu > 

Tel Profile Settings

 option); the ‘Tel Profile Settings’ screen is 

displayed.
